I have a MR3, When i have Paintballs in the gun, Air and a FRESH battery, I am havving issues sometimes ill pull the trigger and it will not fire.. nothign.. no flash from the LED.. pull agian and it will shoot.. I have checked the board everything looks fine. the tank is atleast half full

IF i have no air/paintballs it fires just fine.... the FPS is set at about 250ish

Does this sound like the board on the Egrip is going? if so is there still anyone out there that makes the Boards for this? i know its an older gun but i enjoy using it.
